At those temperatures and pressures, air behaves as an ideal gas. Assuming no change in volume, the most useful equation is the Gay-Lussac Law (P1T1=P2T2). A change of 2 psi cannot be explained by the temperatures that day.
Oh, I agree.
Again, there will be “NEPatriot-centric” arguments made to your calculus (for the record, I am BSChem in the NatGas industry).
In the end...the Colts, with their newbie QB, got spanked by a seasoned NFL team that had a clear goal. All other arguments are just so much “whine”.
I say this as a die-hard, life-long Detroit Lions fan.
